Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an image processing device, an image processing method, and a recording medium. In particular, the invention automatically changes the display settings of image quality and changes the received image quality. An image processing method and a recording medium of an image processing device that can broadcast programs on television, which can often be displayed in the best picture quality. [Knowledge technology] In recent years, digital broadcasting has officially started. For digital broadcasting, video, audio, and other data are compressed and transmitted by MPEG (Moving Picture Experts Group). In digital TV broadcasting, because the data is compressed, compared with analog TV broadcasting, it can broadcast multi-channel high-quality content (programs). However, the conventional television receiver has various functions for setting various picture quality, and the picture quality can be adjusted according to the preference of the user. Due to the development of digital television broadcasting, in addition to the usual moving images, many types of content, such as still images, text and graphics, are required to require more color and subtle image quality adjustments. [Problems to be Solved by the Invention] However, in the conventional television receiver, the picture quality setting is performed by the user ^ After confirming the image with the naked eye, the manual static operation is performed. Therefore, the subtle β setting becomes difficult to use. As a result, the picture quality will not be adjusted according to each program. Even if {renhe shows, they are often viewed with the same picture quality. As a result, there is a problem of making full use of the high performance of the television receiver.

It is considered to have high image quality and lower brightness. Reduce sharpness. Turn off N R (Noise Reduction). Turn off VM (Velocity Modur at ion) (beam speed modulation). Strengthen r correction. For example, the above-mentioned image signal processing parameters are obtained and set from the corresponding table of the MPEG video symbolization parameters and the image signal processing parameters stored in the RAM 9. C P U 8 is based on these image signal processing parameters. By controlling the signal processing in the image signal processing section 6, the subtle gray harmonics, contours, and colors of all dark parts can be displayed with a soft touch, and the texture of the original film can be displayed. In step 6, the image signal processing section 6 processes the brightness signal and color difference signal supplied from the MPEG video demodulator 5 according to the image signal processing parameters set by the CPU 8 to generate an RBG signal and outputs it to the image display section. 7. In step 6, the image display section 7 displays an image according to the R B G signal supplied from the image signal processing section 6. As described above, although the signal processing in the image signal processing section 6 is controlled according to the image processing parameters, as shown in FIG. 4, the image display section 7 may be further controlled. This paper size applies Chinese National Standard (CNS) A4 specification (210 × 297 mm) ~ (Please read the precautions on the back before filling out this page)-Binding-Ordered by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Consumer Cooperative 510996 Printed by the Consumer Cooperative of the Property Bureau A7 ____B7___ V. Invention Description (7) In the present invention, according to the user's preference, the user can also change the setting of image signal processing by operating the user interface 10. Here, the changed image signal processing parameters are memorized in RA Μ9. After that, when the user selects the same program (series of programs), the image signal processing section 6 or image is also controlled according to the same image signal processing parameter. The signal from the display unit 7 processes and displays an image. The invention is applicable to audio signals. For example, when performing signal processing on the data about music programs, the video signal processing described above is performed to display the audio signal, and the audio signal can also be set from the combination of MPEG audio symbolization parameters. Controls the sound signal processing section or the sound output section. In addition, when multiple images are displayed in multiple windows on one screen, the display (output) can be controlled according to the images displayed in each window. In the above, the case where the present invention is applied to a television receiver has been described. However, the present invention is also applicable to IRD (Integrated Receiver / Decoder), and other devices that process digital data (for example, a computer) . Although the above series of processing can be executed by hardware, it can also be executed by software. When a series of software is executed, the programs constituting the software are installed on a dedicated hardware computer or various programs are installed to perform various functions. For example, a general-purpose personal computer is installed from a recording medium. As shown in Figure 1, this recording medium is different from a personal computer. It does not just think that the disk 111 (including the floppy disk) and the optical disk 112 (including CD — R〇) are recorded for the programs distributed by users.
